Roush Saleen Wheel?

I recently picked up a project car that has a set of alleged Saleen wheels. I have searched the internet and have found no good answers. Are the real, what year did they come on, what might they be worth. I have looked at e-bay and found no wheels that look like these; they are 17x7.5 front and 17x8.5 rear, made in Italy is cast on the inside of wheel. So what have I got, I want to use this car for open track events at PIR and will change to a wheel that I can find easy replacements for.

Thanks for the information. It looks like they are real, so I will be getting some track tires and wheels. Off to evil-bay they go in a few weeks for the rat race of the auction house.
Thanks again
